The Codiac RCMP are still asking for help from the public in the ongoing investigation of the shootings that killed three officers and wounded two others in June.

The investigation began shortly after one man was arrested in the shootings of the five constables in Moncton.

Officers started going door-to-door looking for witnesses and people were encouraged to upload any pictures and videos taken during the period of the shootings.

Const. Jullie Rogers-Marsh said the canvassing is complete, although some follow-up might be required.

She said this is an extensive investigation and it will continue until police feel it’s complete.

"It's a very serious incident that we're investigating and unfortunately I don't have a timeline for [completion],” she said.

“We certainly want to do our due diligence and make sure that we investigate everything that we can in regards to the incident."

The RCMP set up a special website that would allow witnesses to upload pictures and videos easily.

Rogers-Marsh said the police are encouraging people to continue sending in any digital evidence that could help their investigation.

"We're encouraging anyone who may be hesitant to send something or may not know if what they really have could be helpful to send it anyway it could be a small piece that could certainly be helpful with the investigation," she said.

Const. Douglas James Larche, 40, Const. Dave Joseph Ross, 32, and Const. Fabrice Georges Gevaudan, 45, were killed while responding to reports of a heavily armed gunman walking through a Moncton neighbourhood on the evening of June 4. Const. Éric Stéphane J. Dubois and Const. Marie Darlene Goguen were wounded.

Justin Bourque, 24, of Moncton, is facing three first-degree murder charges and two attempted murder charges in connection with the shootings.

Along with the criminal investigation being conducted into the shooting, the RCMP is moving forward with an internal review.

RCMP Commissioner Bob Paulson has asked Phonse MacNeil, the former commanding officer of H Division in Nova Scotia, to lead an internal investigation.

"Clearly the death of our three members in the course of duty and the near deaths of many others demand that we seek to fully understand the facts, learn from them and if required, change our practices promptly," said Paulson in a June 25 statement.
